Can Pennywort Be Kept with Fish in Hydroponics? Recommended Hydroponic Flowers Suitable for Keeping Fish

Pennywort grown hydroponically can be kept with fish, but do not keep too many. Keeping just one or two is not only decorative; the fish waste can also meet the plant's nutrient needs, which is very beneficial to its growth. If you keep fish, you must change the water every 2-3 days, to avoid the death of the plant and the small fish from lack of oxygen. Many hydroponic flowers can be kept with fish, such as lucky bamboo, pothos, and elephant ear (Alocasia).

I. Whether fish can be kept

Pennywort can be kept with fish in hydroponics, because its growth ability is very tenacious, and keeping one or two small fish in the container will not affect it. Moreover, the plant's growth requires nutrients to sustain it; if you keep fish, the fish waste can meet the plant's needs. This is because fish waste is a diverse organic fertilizer that the plant can easily absorb.

However, pay attention to the problem of insufficient oxygen. The growth of pennywort and small fish both requires oxygen; if the water lacks oxygen, the small fish being kept will die as a result. So we should change the water every 2-3 days, which will avoid the problem of insufficient oxygen. You can also oxygenate the hydroponic container, but relatively speaking, changing the water is more convenient.

II. What hydroponic flowers can be kept with fish

Many hydroponic flowers can be kept with fish; common ones include pothos, lucky bamboo, peace lily, Monstera deliciosa, pennywort, and elephant ear (Alocasia). These flowers are all very easy to grow and can be kept with fish for decoration. When keeping fish in hydroponics, choose small fish as much as possible; do not keep large fish together with hydroponic flowers. Also, do not keep too many fish; 1-3 is best.
